UNKNOWN: The node requested does not exist.

Hi Team,

I am getting the below error for a filesystem usage monitor on a linux server which is added in Nagios via NCPA. I have checked the server but the filesystem exist on it. This was working before as I am able to see old data and recently this issue happened.


UNKNOWN: The node (/sapmnt/BHD) requested does not exist. You may be trying to access the / node.

what is the reason for this issue and how this can be fixed.

Hi Preethu,

Could you run the following command on the server in question and provide the results:

Code: Select all

 find  /sapmnt/ -maxdepth 1 -ls 

Thanks and Best Regards,

Hi Keith,

I have seen the same issue on another linux server

UNKNOWN: The node (/sapmnt/PQ1) requested does not exist. You may be trying to access the / node. on <node name> Disk Usage on /sapmnt/PQ1 is UNKNOWN.

And I run the command you have given (attached the output).

Hi Preethu,

It looks like the /sapmnt mount point is world readable however it appears you have a problem with filesystems being mounted there. You might want to look through the logs and dmesg output and see if there is anything that indicates a cause. Ultimately this is something you're probably going to have to figure out with your sysadmin/storage teams.

Thanks and Best Regards,
